820 NOT PUMPING GAS
Posted: Fri Jan 01, 2010 11:19 pm
Ok guys, I need some help.
I've got a few 820's available to put on my yellow Lotz '64 SAE repro so I can make it to Adams.
So far two of them, an older original West Bend and a newer US Motors, have good spark, good or great compression, will hold 10 psi crankcase pressure and will fire if I prime them. However they won't continue to run.
Appears that gas is not pumping to the carb - even using my KT 100 starter adapted to the PTO with a long hex and a "jam" sockethead cap screw. Engines turn over very quickly with this starter (got tired of the recoil thing) so they ought to pump just like my KT 100's.
I have a nice new E.C. Carbs HL 306B that I have swapped out for the carbs that came on the engines. Makes no difference. Yes, I've double checked reed cage, gasket and carb pulse ports are all on the same side.
I'm very frustrated and don't want to miss Adams.
Anybody got any ideas?
